Annealing Effects on Ferroelectric Domain Configuration of Tri-Glycine Sulfate

摘要

Annealing effects on the domain configura tion of TGS single crystals are examined with etching the ( 0 1 0 ) plane. The domain of the one annealed at a temperature higher than 70℃ is fine lamellar elongated along the direction perpendicular to the c-axis. The lamellar becomes larger with the lapse of time after the annealing. The change lasts more than 100 days. The moving domain boundaries, during this change, are not caught by dislocations introduced in the process of the crystal growth. The annealing effect on the domain is not related to the annealing time and the cooling rate.
